-LRB- CNN -RRB- At least 10 people and two attackers were killed in Tuesday 's attack against the luxurious Corinthia Hotel in Tripoli , Libya , a spokesman for a security division of the Ministry of Interior in Tripoli said .

Five foreigners -- one American , one French citizen , and three people from Tajikistan -- were killed in the attack , Essam al-Naas said . Five Libyans were killed .

The Libyan branch of ISIS claimed responsibility for the attacks , and released photos of the two gunmen , it said had carried out the attacks as Abu Ibraheem Al-Tunsi and Abu Sulaiman Al-Sudani . Their naming convention indicates that the men were of Tunisian and Sudanese origin , respectively .

Al-Naas said it appears the attackers were Libyans .

American contractor David Berry was among the people killed in a terrorist attack at the Corinthia Hotel in Tripoli , Libya , on Tuesday , according to Cliff Taylor , chief executive officer of Crucible , a security firm where Berry was working .

The FBI is expected to open an investigation into the incident , two U.S. officials told CNN . A State Department official confirmed the death of a U.S. citizen , but would provide no further information .

A French citizen was among those killed , according to the French Foreign Ministry .

Al-Naas earlier said at least two Libyan security personnel had been killed in the attack and that three gunmen were holed up in the hotel .

An online group that supports ISIS said the attack was carried out in the name of Abu Anas al-Libi .

Al-Libi was an alleged al Qaeda operative accused of involvement in the bombing of U.S. embassies in Africa . He was captured by U.S. special forces in Libya . He died in a U.S. hospital this month .

A spokesman for the Corinthia Group in Malta told CNN there had not been a hostage situation in the hotel , as some reports suggested .

`` We are trying to take possession of the hotel back to assess the damage , '' he said , but Libyan security forces were not yet allowing that .

The attack began when militants detonated a car bomb in the parking lot of the hotel . The gunmen then shot their way into the hotel .

Guests were evacuated to safety , however . The five-star hotel is popular among government officials , some of whom reside there .

A witness to the events told CNN that all roads leading to the Corinthia Hotel had been sealed by security forces .

People were warned to stay away , the witness said , adding that there had been exchanges of gunfire .
